TO ALL WHOM IT MAY CONCERN:

Be it known that we, AUGUSTUS P. SHUTE and JOHN F. JACKSON, both of'Charlestown, in the county of Middlesex, and State of' Massachusetts,have invented an improved Extension-Table Slide; and we do herebydeclare that the following is a full and exact description thereof,reference being had to the accompanying drawings, and to the letters ofreference marked thereon.

The nature of our invention consists in providing the sliding bars of anextension-table with narrow metallic strips, running parallel to eachother and longitudinally with the bnrs,but inclined to each other insection, working in corresponding grooves, thus making a neat, strong,and cheap sliding connection for thebars.

To enable others skilled in the art to make and use our invention, wewill proceed to describe its construction and use. In the drawingsiFigure lis a perspective view, showing a set of these bars as theyappear when drawn out.

Figure 2 is an elevation and part section, the elevation beingrepresented as thou-gh cut ofi' on the line Y, iig. 3.

Figure 3 is anl end elevation of our slide. v

We construct our slide as follows We make, of any suitable wood, anumber of bars A B C, and with a circular sa\v,'or with any otherconvenient tool, make the grooves E El parallel to each other in alongitudinal direction, as shown in figs. 1 and 2, but inclined to eachotherin cross-section, as shown in fig. 3. The depth and width of thesegrooves may be varied to suit the reqirements of the onse. A short thinpiece of metal, Dm', Hg. 2, is inserted into the grooves at one end ofeach bar, and made fiist by means of screws or'nails, so

that if two of the bars are put together, as shown by A and B, fig. 3,two of these inelined'metallic pieces DD.

would he attached to B, and wouldslide in the grooves E E ot' A. Eachbar being provided with sets of these metallic pieces D D', &e., it willbe seen that the bars slide upon each other until the metallic piecesstrike eaen other, as shown by D D, fig. 2. '.lo prevent the bars frombeing slipped backwards by each other, pins K K v are inserted into thepieces A and B.

The number of bars would vary to suit the requirements of the table, along table requiring many and a. shortvtable but few.

The'advantages that we 4claim forour invention are extreme simplicity,eheapness, and durability.

Having thus described our invention, we will'proceed to set forth ourclaim.

What we claim as our invention, and desire to secure by Letters Patent,is

The combination, as well as the arrangement, of the metallic slips D DDIl with the grooves E E and the bars` A B C, made substantially asdescribed and for the purpose set forth.
